Seunshare, /tmp directories, and the "sticky" bit

Seunshare, /tmp directories, and the "sticky" bit

I'm confused why when ksu was run, it didn't get it's own /tmp....

There was a mini-kernel os called vsta which worked this way. Every user saw the /tmp directory as their own. Changing the euid changed the contents of the /tmp directory.

This can be done nicely in SELinux, or even without it (ab)using PAM. I don't know if it was widely publicised though.

Russell Coker did give a few presentations on this that may be online.
